Where is Smaug?

Benedict Cumberbatch, the actor who does the voice of Smaug, the dragon and main antagonist in The Hobbit, says that we will only get a glimpse of Smaug in the first film. According to him, all we will get to see is the eye of the red wyrm near the conclusion of The Hobbit: An Unexpected Journey. Unfortunately, I don't have any pictures again, but I didn't expect to find any, because Smaug appears at the end of the movie and he will be (I'm expecting) the main advertising theme for the next movie.
